Coordinator: Tran Ngoc Bao, Ph.D

Implementing Institution: Information Technology Office, HCMC University of Education

Duration: from 04/2011     to 04/2012

1. Objectives:

Wireless local area networks have become more and more popular. They had been installed by businesses of all types. The IEEE 802.11 standards were developed for WLAN. However, sources have shown that even the new standards are flawed, allowing attackers to perpetrate attacks. Our works focus on man-in-the-middle attacks, a type of attacks that can be used to steal passwords and to disrupt key exchange operations. This project presents a software solution – called AMIMA (Against Man-in-the-Middle Attacks), to defend against this type of attacks. In this solution, the “delayed password disclosure” technique is used for authentication phase, IPSec and VPN technique will be used for data exchange phase.

2. Main contents

-        Survey of Access Control in WLAN: authenticate user through devices that support wireless connectivity via IEEE 802.11 protocol known as client or workstations to ensure that only the authenticated legal client will be granted access to the wireless network and wired network is connected via wireless network known as access point.

-        Proposes solution: Against Man-in-the-Middle Attack (AMIMA) using delayed password disclosure technique.

3. Results obtained:

To science, the results of basic research are publiced in the Computer Science journals. These are:
